s4 problem,need some help

just switched on my s4 to do a mix and realised that the exclamation symble above the snap button is flashing,just want to know if anyone knows what that is about?

I think it means your computer is not on a power source i.e., not charging. I noticed it too until i plugged my computer in and it stopped.

Or it comes on if your output volume is turned down too low, I have monitors plugged into my s2 so I have to keep it low, pro 8's annoy neighbours
